Steel is an alloy of iron and carbon containing less than 2 per cent of carbon and 1 per cent of manganese (and small amounts of silicon, phosphorous, sulphur and oxygen).

But carbon dioxide is carbon dioxide.

The question whether carbon or silicate grains will form critically depends on the chemical composition of the Jovian atmosphere.

Total emissions of HFCs, PFCs and SF6 (gigagrams of CO2 equivalent)

There's diatoms made out of SIO2, and they're magnetotactic bacteria that make small, single domain magnets used for navigation.

1 GT (or gigatonne) CO2 equivalent means 1,000 million of tonnes of CO2.

MT (or mega tonne) of CO2 equivalent means 1,000,000 tonnes of CO2.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

At a minimum, information should be provided on the following greenhouse gases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulphur hexafluoride (SF6).

Limitation and reduction of emissions of hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. Annex B

I personally think the surviving intelligent life form on earth is not going to be carbon based it's going to be silicon based.

For Sri Lanka, the greater concern is on account of the entry into the lungs of human beings of toxic gases and particulate matter, including carbon monoxide, hydrocarbons, nitrous oxide, sulphur dioxide and airborne carbon and lead.

Fluorocarbons and SF6

The share of process emissions from industry (CO2 and PFCs) is particularly high.

7.9 quot Tonne of carbon equivalent quot means the amount of carbon dioxide (or other greenhouse gas calculated by global warming potential) in terms of tonnes of carbon (44 12 of one tonne of carbon dioxide is equal to one tonne of carbon).

quot Tonne of carbon equivalent quot means the amount of carbon dioxide (or other greenhouse gas calculated by GWP) in terms of tonnes of carbon (44 12 of one tonne of carbon dioxide is equal to one tonne of carbon).

Active optics, computer assisted polishing and ion shaping of mirrors, and silicon carbide mirror technology were typical examples of applications of new technologies for astronomical optics manufacturing.

Modern sex dolls have evolved into robots with a silicon skin.

Haven't you ever heard of carbon monoxide? It kills people. It does?

Here's an interesting one for the IT world bio silicon. This is a diatom, which is made of silicates.

Eighteen Parties (15 per cent) provided estimates of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and or sulphur hexafluoride (SF6).

Companies switching from CFCs to other substances were accumulating growing volumes of CFCs for disposal, but could not keep them in storage indefinitely, and lacked the technical and financial capacity to destroy them.

Cars and trucks add up to about 25 percent of the world's CO2 emissions.

Many Parties mentioned in this regard the substitution of chlorofluorocarbons (CFCs) by HFCs.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

Carbon dioxide (CO2) Fuel combustion

They indicate that CO2 emissions are projected to decrease by 33 per cent, CO by 40 per cent, NOx by 8 per cent and NMVOC by 27 per cent.

The correction for electricity trade amounts to approximately 11 per cent of total gross CO2 emissions in 1990, which totalled 58,400 Gg. Carbon sequestration from land use change and forestry was estimated to be about 2,600 Gg of CO2.
